000009258 520__ $$2eng$$aThe occurrence of shrinkage in concrete leads to development of internal tension stresses which can result in concrete cracking. The presence of cracks in concrete creates pathways that ease the access of aggressive agents reducing concrete structure durability and service life. Consequently, the correct reduction of shrinkage strain during the designing process is important to assure the structure’s durability and long time serviceability. In light of this, the objective of this research was to develop an experimental based fuzzy logic model to predicting self-compacting concrete shrinkage. The fuzzy logic model decision-making is optimized though an evolutionary computing method, therefore enhancing computational effectiveness. The obtained results are compared to the B3 shrinkage prediction model and statistical analysis, indicating the reliability of the proposed model, are presented.
